[PATCH 3.19.y-ckt 066/102] usb: musb: fix order of conditions for assigning end point operations

[Kamal Mostafa]

3.19.8-ckt3 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ben Hutchings <ben@xxxxxxxxxxxxxxx>

commit da96cfc133350024ba68ef3289faeb539ee13872 upstream.

Currently we always assign one of the two common implementations of
ep_offset and ep_select operations, overwriting any platform-specific
implementations.

Fixes: d026e9c76aac ("usb: musb: Change end point selection to use ...")
